15-MU-M EMISSION FT SPECTRA OF (CO2)-C-12-O-16 EXCITED TO HIGH VIBRATIONAL LEVELS

Emission spectra of CO2, vibrationally excited by a dc electric discharge. were recorded with a resolution of 0.006 cm-1 using a Fourier Transform Spectrometer (Bruker 120HR), in the spectral range of 13-18 μm. Results concerning 43 vibrational transitions with υ3 = 0 of 12C 16O2 are reported. The band centers and the spectroscopic constants for all the vibrational levels involved are given. They reproduced the experimental wavenumbers with an rms of the order of 6 × 10-5 cm-1 for the very best vibrational transition and of 2 × 10-4 cm-1 for most of the others. © 1993 Academic Press.
